Which of the following is a benefit of using Summary Fields?

Using Summary Fields provides the significant benefit of automatically calculating totals from child records. This means that when you set up a Summary Field within a parent table, it can aggregate data from multiple related records in a child table. For instance, if you have a parent record for a customer and child records for transactions, a Summary Field could calculate the total dollar amount spent by that customer by summing up the transaction amounts.

This functionality is particularly advantageous because it simplifies the process of data analysis and reporting. Instead of manually calculating totals or creating complex queries to gather this information, Summary Fields streamline the process, improve data accuracy, and enhance productivity. They allow users to view aggregated data in a consolidated fashion, making it easier to derive insights and make informed business decisions based on that data.

Other options, while relevant to Quickbase functionality, do not specifically pertain to the core purpose of Summary Fields. Custom user interfaces, linking unrelated data tables, and displaying real-time data analytics address different aspects of database management and user experience but do not provide the aggregation feature that Summary Fields are designed for.
